Application tiled September 29, 1888. Serial No. 286,814. (No model.)

To @ZZ ufwnt it may concern.:

in the county of Pike and State of Mississippi, have invented certain new and useful Improvements in IVire-IVound Guns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to gun-barrels, large and small, and especially to high-power guns and other'rifled guns liable to great torsional as well as longitudinal and radial or bending or drooping strain.

The` invention consists in the construction of a gun-barrel and the combination of the parte composingthe same in the manner sub stantially as hereinafter stated.

The object of the invention is to combine in a gun-barrel a great degree of longitudinal strength with little weight and to make a barrel strong against torsional strain; also, to secure the wire coils iirmly to each other and to the gun and to provide a chamber which will give'an air-space around a cartridge-shell and permit the ignition of the second or third charge of an accelerating-cartridge within said chamberafter the projectile is. in motion along the barrel; also, to provide a suitable lining andonter jacket for said guns.

Figure l is a side elevation of-a gun having a barrel of my improved constructiomapart being broken away. Fig. 2 is alongitudinal section of a part of the barrel, a modified detail beingshown detached. Fig. 3 isa crosssection of the barrel,sho\ving the lines grooved and notched- Fig. 4 is a longitudinal section at the muzzle. Figs. 5 and (5 are sections longitudinally of the chamber and base of the bore, showing a cartridge in position. Fig.

5 is a longitudinal section of a wire-wound,

gun, showing one form of jacketing the saine. Fig. 5b is a horizontal section showing a modified form of Fig. 5, in whichthe forward porjacket or sleeve is fitted loosely over the wire. Fig. 6 .has a sectionshowing my method of wire-Wrapping the tube A and se- Fig. '7 is a perspective detail of cable and fastening.

The letter A denotes the initial tube of the gun. This tube may be cast or forged of steel, aluminium bronze, orother strong metal. The tube is riiled in the bore I3 with a very rapid twist and is therefore subject to great torsional strain in firing. The tube has external ribs or spiral flutesC extending from the eX panded base A to the muzzle or near the 'muzzle These spiral ribs should have nearl7 the same twist as the riding, but should turf.A in the opposite direction. The ribs may in castor Vfoged on the tube, or a solid cylindet may be shaped to leave the ribs.

Between each-pair of ribs C C, I place a rod or cable E, preferably of steel and anchored firmly to the base A of the barrel and also to the muzzle-rin g F or held between the muwle and its ring.

' The strengthening rod orlcabiel may be held by a screw-thread in the base-piece, as 7o at F3, or may pass through, as at F4, and be secured by a nut F5. Soat the front a nut F may be attached to the rod or cable and this covered by the muzzle-'ring F. Thus a eontinuous length'ofwire or cable may be used, 75

or the pie-ces may be of suoli length as to ex.- tendnearly from the breech to the muzzle -and be fastenedatfeaoh end, the muzzle-nut affording a means of putting/ in initial strain on the'cable atall times.

A sleeve II is applied to the base tocover der II5 extending'overthe lining at the muz- 85 zle, if one is used. p This sleeve can' be readily shrunk on either to the base A and held by a'ridoed '.oi'nt IIS, Fie'. 2 o rj-a sleeve II' which.

o .J o a a 'surrounds said baseat the rear andinas a prevent forward"movement, 9o

shouldeiwll2 to as in Fig. 5. In the latter ligure the yrodsare brought into Contact with eachother around-v thechamber'and inside the sleeve, thespiral .ribs .being OlIllij-ea lfIQnl the. base lOf the tubearound the'chamber. :y 'Y

The' detail Fig. '7 shows an enlargement E' at 'the endl of the cable or rod-E, saldenlargement being polygonal, so aste rest in a recess near the base of the gun and so as not toturnftherein... The effect of the ribs C will be to strengthen the tube aga-inst torsional strain; The cables IOO f gether, as'shown in base, Fig. 5, and after one or more layers of wire have been put on the whole gun may be put into a bath and subjectedto the electroplating proce'ss and suitable metal deposited on the wire wrapping and the gun, so as to secure the coils firmly to' each other and to the gun. Another layer of wire will then be wrapped over that already secured to the gun by the electro process and the gun again subjected to the electroplating process and the second layer of wire coils secured firmly in place.n Additional lay'ers of coiled wire of any desiredform, either-large or small, will be put on in the same `manner and by the same process until sufficient wire has been put on and all secured fby electroplatin g and all crevices and cracks filled lby the plating process. The outside of the gn may then be turned down and a light jacket or tube put on, which extends to the muzzle and has shoulders H2 and II5, as shown in dotted lines and in section, Figs. 5 and 5a, and which jacket' forms the support for the breech-block atthe rear. Fig: ralso shows the reary portion of the jacketv carrying the breech-block support. The jacket will be made inl sections and united bya lockingjoint,\as shown in Figs. 5, 5, and 5b, and a hoop H4 'will preferably be secured over the joint, as shown in Adotted lines in The Vgreat advantage of securing the coils of Wire on the gun by the electroplating proces's, using either copper, nickel, aluminium bronze, or other suitable metal, is that the .fine temper of the wire, which is preferably of steel or aluminium bronze, is not injured in the least, and it can be more iirmly secured by the electroplating process than any other I know of. The end of thewire inthe beginning can be irm'ly anchored, and after the first wrappingk the wire need not be cut .or broken; but the electric current may be put on bysing the coil of ywire which is be ing wrapped on the gun as the conductor, if

`sofdcsired, and afterihe firs( eoiis-havehmn made integral with thegun. and eachother by the metal electrodeposted other and continuous layers of wire'can'b'e put on without a break, if so desired, iu thev wire until'the wrappings are completed. j

In Fig. 6 the tube A has a series of coils of wire O wound around it and secured to the gun and each other by the metal o o electrodeposited thereon.

I am not aware that any one has heretofore made, shown, or described a wire-wound gun having the wire winding .extending from the breech to the muzzle and a covering or jacket superimposed over the wire, and I desire' protcction, broadly, for myinvention` without regard to the means I employ for covering said Wire, the rear-portion of said jacket forming a support for the breech-block of the gun.

It is apparent that many modifications may be made of this invention without departing from the letter and spirit and scope of the same.

I claim-- 1. A wire-wound gun having the wire covered by a jacket extending from the muzzle to the breech end of the gun, said jacket being arranged to support the breech-block and take the strain caused by the discharge of the gun.

2. A gun having spiral ribs on the outside vof the barrel, the spaces between the same being wire-wrapped, and means for securing the terminals of said wire and applying tension thereto, as set forth.

3. A jacket for wire-wound guns having the wire extending from the breech to the muzzle-section, composed of two or more tul bular sections united and extending over said wire from the muzzle-section to the breech of the gun.

4f. In a gun, a central core wire-Wound or wire-wrapped, and a casing or covering consisting of a jacket united to a tube superimposed over said wire and extending to and secured to the muzzle-section of said gun.

5. A wire-wound gun covered by two or more uniting interlocking jackets, hoops or tubes superimposed thereon, one of which projects rearward therefrom carrying the breech-block support and the other projecting to the muzzle-section of said gun.

6. A gun provided with or composed of a central core,tube or barrel and having thereon an overlying seamless tube or casing with outwardly-extending ribs or fiuting thereon, said casing extending to or' near the muzzle, substantially as described.

7. A gun having spiral ribs on the outside of the barrel the spaces between the same being wire-wrapped and means for securing the terminals of said wire, substantially as describedr In testimony whereof I aiiix my signature in presence of two witnesses.
